Solve the following inequality<br> 9x−2&gt;43
MrRissso [65]

Answer: x > 5

Explanation: First we want to look at our variable and ask ourselves what's happening to it. Since 2 is being subtracted from 9x, we always undo addition and subtraction first so we add 2 to both sides.

That gives us 9x > 45.

Now we need to undo multiplication and division. Since 9 is being multiplied by <em>x</em>, to get <em>x</em> by itself, we need to divide by 9 on the left side of the inequality. If we divide by 9 on the left side, we must also divide by 9 on the right side.

This leaves us with <em>x > 5</em> which is the solution to this inequality.
